Accentize dxRevive.

Restore a narrow-band recording

In a telephone conversation or an old recording, parts of the frequencies important for legibility may be missing. dxRevive evaluates speech and tries to restore such components. In the guide, Pro Accentize describes several neural network algorithms. The choice is useful to make on a short fragment. Even when the recording becomes clearer, too much processing can change the timbre, so the source should be stored separately.

Check consonants in a quiet line

Take your short dialogue recorded on an old recorder. Choose a place where the person speaks quietly and at the end of the phrase you can hear hissing. Save the original volume as a reference, then apply the plugin to the copy. Compare both versions at a close level. Check if the words have become clearer and whether an artificial sound has appeared after the consonants.

Then place the processed passage between two adjacent lines. If the voice suddenly sounds different, reduce the amount of processing or apply it only to the part that needs repair.

Working in an editing project

Before processing several takes, check which plug-in formats your audio software supports. Accentize describes rendering a selected passage separately when real-time processing is too demanding. Compare it with processing during playback. Save the settings and the exact boundaries of the edit so you can go back to the original when the cut changes. The base and advanced editions offer different algorithms. Listen to the pause after the quietest line as well.
